This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole's event horizon, where no light can escape the massive object's gravitational grip. The black hole's powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared as the stars skim by the black hole. Credit: NASA, ESA, and D.

This artist’s concept visualizes a super-Neptune world orbiting a low-mass star near the center of our Milky Way galaxy. Scientists recently discovered such a system that may break the current record for fastest exoplanet system, traveling at least 1.2 million miles per hour, or 540 kilometers per second.

Discover the Fiery Beauty of NGC 2040—A Star Cluster in Cosmic Bloom

February 16, 2025

This is an 80-million-pixel picture of the star cluster RCW 38, located 5500 light-years away in the constellation Vela. RCW 38 is a young cluster containing about 2000 stars, and is bursting with star-forming activity. The picture was taken with ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA), operating in Chile's Atacama Desert. It shows a mixture of gas, dust and stars, creating an extravagant, yet spectacular landscape. As VISTA observes infrared light, it is able to peer through most of the dust in this region, which would block our view when observing in visible light. Behind the dust, VISTA is showing young stars within dusty cocoons and cold 'failed' stars known as brown dwarfs, thus revealing the secrets within these young stellar nurseries.

This image of Westerlund 1, one of the most massive young super star clusters in the Milky Way, combines data from JWST’s MIRI and NIRCam instruments to reveal detailed structures within the cluster's environment. The color image reveals intricate details of gas and dust in the cluster, with longer-wavelength mid-infrared emission (red) highlighting warm dust and gas, shorter mid-infrared emission (green) tracing complex structures of cooler dust and gas, and near-infrared emission (blue) showcasing the brilliant light of young, massive stars embedded in this cluster. These observations provide important insights into how stellar winds and radiation from massive stars interact with the surrounding material, shaping the cluster's morphology and influencing its evolution.

Galactic Fireworks Display: Massive Stars in Action at Westerlund 1

This striking image was taken by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3, a powerful instrument installed on the telescope in 2009. WFC3 is responsible for many of Hubble’s most breathtaking and iconic photographs, including Pictures of the Week. Shown here, NGC 7773 is a beautiful example of a barred spiral galaxy. A luminous bar-shaped structure cuts prominently through the galaxy's bright core, extending to the inner boundary of NGC 7773's sweeping, pinwheel-like spiral arms. Astronomers think that these bar structures emerge later in the lifetime of a galaxy, as star-forming material makes its way towards the galactic centre — younger spirals do not feature barred structures as often as older spirals do, suggesting that bars are a sign of galactic maturity. They are also thought to act as stellar nurseries, as they gleam brightly with copious numbers of youthful stars. Our galaxy, the Milky Way, is thought to be a barred spiral like NGC 7773. By studying galactic specimens such as NGC 7773 throughout the Universe, researchers hope to learn more about the processes that have shaped — and continue to shape — our cosmic home.
